So, after I finished replacing my CV joints I found out the side gear shaft on the passenger side is what I would call loose and has a good amount of play. What is the best way to fix this and do I need to replace the differential or just the oil seal or the side gear shaft?

 

For some reason they all do that. How much play I don't know but most i've dealt with have a pretty good amount of play. As long as your axle seal doesn't leak you should be fine

 

one time mine actually slipped out and leaked gear oil everywhere..... my torsion bars are cranked thats why it happened

 

ok maybe its just my cv shaft

 

I'm sure its ok. Is it leaking oil out of the diff? Do you have any major vibrations?

 

no leaks vibration off and on from 30mph up to 70mph after 70mph gets really bad

 

Not in 4wd I hope. If your vibration is just in 2wd check the output flange of your tcase. Alot of times the nut backs off giving some play to the driveshaft. As far as your front, if you arn;t leaking, you're good

 

ok will cheek that thanks for the help

 

Every high mileage IFS box I have torn down has that problem; and consider it one of Toyota's small engineering flaws. In fact; if you turn hard and slowly moved forward you probably will mistake it for a failing CV joint. I did.

I suggest this "fix" be added to a tech FAQ

Hit the boneyard and buy an ADD IFS. You will notice it has needle bearings instead of a brass bushing on the passenger side. (The brass bushing has worn and is not spared as best I can tell)

You will have to swap your passenger tube and long axle stub over and add a oil seal that is used in the non ADD box. I would also use the short stub shaft that came with the doner ADD box; as the old one probably show wear.

And while you have it out; toss a locker in there

I grab ADD IFS boxes when I shop the bone yards for this reason, I have 2 IFS trucks.

 

Not to pick a fight; but you are not. The C Clip will wear and the shaft can unseat it self.

I would not run a BJ spacer on a truck with this issue; or wheel too hard.

 

well after much reeding i have a ADD dif im going to get a new cv and see what happens

its my girls i have the truck no off road and no lift lol
